Abstract
A smokeless gas generator composition with an oxygenated binder such as a polyester or a polyether allows higher binder content with less solid oxidizer additives such as guanidine nitrate or ammonium nitrate and allows the composition to be cast.
Claims
exact text as granted — not AI-modifiedWhat is claimed:
1. A castable gas generator composition comprising: between 25 and 40 weight percent of a binder of polyether or polyester; between 45 and 60 weight percent ammonium nitrate coated with a compound selected from the group consisting of magnesium oxide and magnesium nitrate; and an effective amount of burn rate modifier.
2. The composition of claim 1 wherein said binder contains pendant oxygen-containing groups.
3. The composition of claim 2 wherein said binder is a carboxyl terminated polyester.
4. The composition of claim 1 wherein said burn rate modifier is guanidine nitrate.
5. The composition of claim 4 wherein said binder contains pendant oxygen-containing groups.
6. The composition of claim 5 wherein said binder is polydiethylene glycol adipate.Cited by (0)
